SASH LOCK. i

Applicationfilled August 13, 1923. Serial No, 857,141.

To all whom it may concern:

Be it known that I, GEORGE A. BERRY, a citizen of the United States, and a resident of Modesto, county of Stanislaus, State of California, have invented a new and useful Sash Look, of which the following is a specification.

This invention relates to sash locks and has for its primary object the provision of a simple and inexpensive device of this character which may be conveniently and quickly applied to a sliding sash of usual construction which will include novel means to engage with the sash guide of window rame or casing, to coact therewith and hold and in such manner that will render it *ceedingly difficult, if not impossible, to open the sash from the outside.

Another object of the invention is to provide a lock of this character which. can be adjusted with dispatch as the occasion re; quires and which will include a movable bolt and means for yieldingly holding same in any intended position of adjustment and in a manner to prevent undue rattling of the parts under the action of wind.

My invention, therefore, comprises cer tain new features of construction and arrangement and combination of elements hereinafter set forth and pointed out in the claims annexed hereto.

In thedrawings: V V

Figure 2 is a horizontal section on line 22 of Figure 1;

In carrying the invention into practice use is made of a'sliding sash (5) of. usual well known constru ction, the same mounted to slide vertically in the guide (6) of a window frame The inner bar of the guide groove (6) is formed with a vertical series of recesses (8) which may be suitably spaced apart. Adapted to register with any one of these reces es is an peni g formed in the side rail of the sliding sashi" l dounted to slide in the opening (9) is a bolt (10) having a cylindrical end'(l1) adapted to be projected into'any one ofthe aforesaid recesses (8) and-to hold the-sash (5) in a definite or fixed position of ad justmenta This bolt is also slidable in an opening (12) of the guide plate" (18) which issecured by fastenings (14) to the side rail of the sash (5) as clearly shown in Figures 1 and 2 of the drawings. Mounted upon the guide plate (13) so as to traverse the opening (12) at one side of the center thereof is a keeper bar or strip (1 1) the purpose of which will inafter; r i

The bolt (11) is formed on itsopposite sides with grooves (15-15) At one side the bolt is recessed or cutaway at (16) so as to form a tapered nose (17) overwhich may be referred to herebe extended the loop or bight (18) of ii substantially V shaped spring (19). This spring is formed of a smgle piece of wire which inherently persuades lateralseparation from one another of the leg (20). These legs are accommodated manipulating loops 21) ,andsame are located respectively at the opposite sides of a manipulating lip (22) on the outer end of in grooves (15 15) of the bolt and they are extended Ata' point outwardly of the openingsaid bolt. In this manner it ismanifest that when the bolt is adjusted to any one of its respective positions itv'is yieldingly held against casual movement away from this position. This is due tothe fact that the legs (20) of the spring bar are held. with sufficient yielding force against thediametrically opposite points of'the opening (12') to create friction between the parts. When it isjde sired to free the bolt in'order thatit'c'an he lOO moved in its opening (9) the manipulating loops (21) are grasped betweenthe fingers A of the hand and brought together toward the lip (22) of the'bolt. The legs, (20)" 'are then moved "outfof frictional engagement with the walls'of the opening (1.2).. -The spring is so designed that maximum adj ustment of the bolt may be made in either direction and the bolt may be satisfactorily held in its intended position of adjustment.

When the bolt is moved to the dotted line position shown in Figure l the sash may be raised or lowered and the opening (9) brought into registration with a selected recess The bolt is then moved to the full line position shown in Figure 1 in order that its cylindrical end (11) will be seated in said recess The sash is now secured in its adjusted position. It shall be understood that the bolt may be applied to either the upper or lower sash. If desired both sashes may be equipped with my invention.

In order to prevent accidental or full withdrawal of the bolt from the opening 9) I provide same with a .recess which accommodates the plate or keeper (l t). The wall (24.) of the recess constitutes a stop to coact with said plate or keeper (is) when the bolt is withdrawn to the limit of outward movement. Aside from functioning in this manner the bolt is held against rota- 'ti'on so as to hold the loops (21) of the spring (19) always in superposed positions and substantially parallel to the horizontal lip (22). The purpose of this dual fimctioning of the parts is to always expose the loops (21) where they may be conveniently grasped between the fingers of the h and and manipulated as deSied.
